I've been toying around with WPMU for a few days now before replacing my old WP with it, trying to get a feel for things. I just had a few questions I haven't been able to find answers to.
First off, the whole plugins thing confuses me. If you disable Site Admin->Options->Menus->Plugins, blog owners don't have the ability to mess with plugins at all, but does that mean they dont have any plugins at all? Is there a way to create a default set of plugins and have them configured?
Also, is there any way to disallow certain actions on users' blogs? I want to be able to, say, use a certain template for my blog but not allow other users to use it. I'd also like to be able to have a dynamic sidebar like I have now, without the ability for other users to change it.
